Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a cylindrical roll-up base paper or fiber, metal, petrochemical product, etc. formed by winding base paper for cardboard boxes, printing and packaging boxes. The present invention relates to a storage / conveyance mechanism for accommodating and transporting a mainly cylindrical container such as a cylindrical container such as a drum or a drum.

[Problems to be Solved by Prior Art and Invention]

For example, as shown in FIG. 6, the contained materials P such as the winding base paper are stacked and arranged in a plurality of upper and lower sections in a plurality of compartments S provided on both sides in the width direction of the normal warehouse W, and are arranged in the center of the width direction of the warehouse W. Is provided with a passage T for traveling the clamp lift L for gripping and carrying the contained object P. In the work of gripping and transporting the contents P, the clamp lift L is orthogonal to the length direction of the passage T,
That is, the stored object P is grasped by going straight in the width direction of the passage T. When the object P is to be gripped while being slanted in the lengthwise direction of the passage T, the clamp lift L is prevented from advancing by the adjacent object P as shown by the two-dot chain line in the figure, and the desired object P is accommodated. The object P cannot be gripped. Therefore, the width of the passage T needs to be considerably longer than the entire length of the clamp lift L in consideration of the minimum turning radius of the clamp lift L, and the space for accommodating the contents P in the warehouse W is limited accordingly. It

In addition, there are many types of stored items P depending on their widths and materials (for example, more than 100 types of winding base paper only), and in terms of transport workability, each type has a predetermined section S of the warehouse W. Ideally, it should be housed in. However, in such a case, a considerable space is required due to the large number of types, so normally, several types are mixedly arranged in one section. As a result, when the desired article P is not located on the side of the passage T in the section S, the article P located on the front side of the desired article P is once moved to another location to move the desired article P to the desired position. Take out,
The work of returning the unnecessary contents P to the original place again is necessary, and there is a problem in workability.

Further, even when the same type of stored items P are stored in the same section S, it is preferable to use the stored items P in the oldest stored order from the viewpoint of quality maintenance.
The stored items P in the inner part of the section S are used for a long period of time because the stored item P is newly stored on the front side before the stored item P in the rear part of the section S is used. The situation occurs that there is no.

In order to solve these problems, an automated warehouse using a moving rack is also provided, but the automated warehouse cannot be used in a small space because of its large mechanism. Further, since the mechanism of the moving rack is an integral structure, it cannot be partially added, and furthermore, it is difficult to move the moving place of the stored item as needed. In addition, since the control system of the automatic warehouse is the overall control system, it is not possible to simultaneously move and provide different kinds of desired contents to a plurality of places, and always move and provide one kind of contents to one place. I can only do things. Further, since the entire mechanism is always operated by the overall control, its power consumption becomes large.

An object of the present invention is to enable the lift vehicle to take in and out the contained items even if the width of the lift vehicle traveling passage such as a clamp lift is set shorter than the width required for the lift vehicle to rotate. In this way, the space of the warehouse can be effectively used for accommodating the contained items, the workability of taking out the contained items is improved, and the stored items can be used in the old order. The present invention is to provide a storage and transport mechanism.

Another object of the present invention is to provide a storage / conveyance mechanism capable of simultaneously moving different kinds of desired storages in a plurality of locations and consuming less power.

[Means for Solving the Problems]

In order to achieve the above object, in the device according to claim 1,
Driving means for supporting a plurality of placing means on which the contents are placed by the annularly arranged supporting means, and for moving the placing means along an annular path formed by the supporting means. To form an accommodating / conveying device, and a plurality of accommodating / conveying devices are arranged side by side along a path for traveling of the lifting vehicle so that the lifting vehicle can obliquely approach the accommodating / conveying device. The gist of the present invention is that the corner portion on the passage side of the accommodating and conveying device is notched and the width of the passage is set shorter than the width required for the lift vehicle to rotate.

Further, the invention according to claim 2 is characterized in that, in the accommodating / conveying mechanism according to claim 1, a remote controller capable of separately controlling drive of a plurality of accommodating / conveying devices is provided.

[Action]

In the device according to the first aspect of the present invention, by the above means, the loading means is moved along the annular path by the driving means, so that the contents are conveyed and arranged at a desired position on the annular path. Then, in a state in which the desired contained item is conveyed to the passage side, the lift vehicle obliquely approaches the corner portion of the accommodation conveying device, and the contained item on the passage side can be taken out. Therefore, even if the width is set shorter than the width required for the lift vehicle to rotate, it is possible for the lift vehicle to take in and out of the contents, and the space such as a warehouse can be effectively used for accommodating the contents. The workability of taking out the contained items is improved, and the contained items can be used in the old order.

According to the second aspect of the invention, by individually operating each of the accommodating / conveying devices and moving the mounting means, desired accommodating objects are respectively conveyed and arranged on the passage side of each device, and the accommodating objects are moved. Power consumption can be suppressed by stopping the driving means of the accommodating / conveying device that does not need to be moved.

〔Example〕

An accommodating / conveying device D according to an embodiment of the present invention will be described with reference to FIGS.

As shown in FIG. 1, a plurality of roller conveyors 2 are arranged and fixed in a substantially octagonal ring shape along the outer peripheral shape of the base 1 on an octagonal plate-shaped base 1 having corners 1a at four corners. Inside the outer supporting means O, a plurality of large and small roller conveyors 3 are arranged and fixed in a substantially octagonal ring shape substantially corresponding to the outer supporting means O to form the inner supporting means I. Between the outer supporting means O and the inner supporting means I, eight sprockets 4 and 4A are fixedly arranged on the base plate 1 at predetermined intervals corresponding to the arrangement shape of the outer supporting means O, and the sprockets are also arranged. A chain 5 is attached to 4, 4A, and the chain 5 forms an octagonal ring-shaped path R.

Six support shafts 6 are integrally formed on the upper surface of the chain 5 at equal intervals in the traveling direction (see FIG. 2), and each support shaft 6 has a mounting circle as a container P mounting means. The center holes 7a of the plates 7 and 7A are fitted so as to be relatively rotatable. As shown in FIG. 3, the tops of the peripheral surfaces of the rollers 2a, 3a of the roller conveyors 2, 3 of the outer supporting means O and the inner supporting means I and the upper surface of the chain 5 are flush with each other, and the mounting disc 7 The lower surfaces of 7A and 7A are the peripheral surfaces of rollers 2a and 3a of inner and outer supporting means I and O, and chain
It is designed to be supported by the upper surface. Considering that the space between the adjacent mounting disks 7 and 7A is the narrowest at the corner 1a of the base 1, both mounting disks 7 and 7A have corners.
It is necessary to determine the size of the mounting disks 7 and 7A within the range of the diameter so as not to collide with 1a. Further, preferably, the roller 2a, 3a of each roller conveyor 2, 3 is coated with a lubricating oil, and the mounting disc
Make 7,7A smoothly move on the rollers 2a, 3a.

A motor 8 capable of rotating in the forward and reverse directions is provided as a driving means inside the inner side supporting means I, and a speed reducer 9 is drivingly connected to the motor 8. The pair of drive sprockets 10 provided in the decelerator 9 include two sprocket wheels on the left side in FIG.
4A Driven sprocket 11 fixed to the upper surface so that it can rotate integrally
Are drive-coupled via a drive chain 12. A control box 13 is electrically connected to the motor 8, and a remote controller (not shown) is electrically connected to the control box 13 so that the remote controller can remotely drive and control the motor 8 via the control box 13. Has become. Then, by operating the remote controller to drive and control the motor 8, the chain 5 travels via the speed reducer 9, the drive chain 12, the driven sprocket 11 and the sprockets 4 and 4A, and is supported as the chain 5 travels. The mounting disks 7 and 7A can be moved along the annular path R described above via the shaft 6 and can be stopped at a desired position.

The accommodating / conveying device D configured as described above is, for example, the fourth
As shown in the figure, a plurality of storage and transfer mechanisms are arranged in parallel on both sides of the warehouse W in the width direction. In this mechanism, different types of stored objects P are stacked on the mounting disks 7 and 7A of each device D in a plurality of upper and lower layers.

In order to take out a desired type of stored object P from the storage / transportation mechanism, first, a storage / transportation device D that stores the desired type of storage item P (for example, the rightmost storage / transportation device D in the upper row in FIG. 4). The motor 8 is driven and controlled by a remote controller so that the mounting disks 7 and 7A on which the desired contents P are mounted are held at a predetermined gripping position on the passage T side (for example, the mounting circles shown in FIGS. 1 and 4). Board 7
Move to position A) and stop.

Then, after advancing the clamp lift L in the length direction of the passage T, the clamp lift L is placed in front of the mounting disc 7A at the gripping position while being slanted in the length direction of the passage T as shown in FIG. The clamp lift L is further advanced so as to face the disk 7A, and the uppermost container P on the mounting disk 7A at the gripping position is gripped by the clamp lift L. At this time, the storage / conveyance device D
Since the base 1 has the corners 1a at the four corners, when the clamp lift L approaches the device D, its front wheel (the left front wheel in FIG. 4) is located at the corner 1a and the base 1 collides with the front wheel. Therefore, the progress of the clamp lift L is not hindered. Therefore, the clamp lift L can grip the contained object P in the direction of 45 ° with respect to the length direction of the passage T.

When the clamp lift L grips a desired storage object P, the clamp lift L is slightly retracted in a state where the clamp lift L is skewed in the length direction of the passage T, and when the clamp lift L comes to a position where it does not interfere with the storage / conveyance device D, the clamp lift L is moved. L is retracted in the direction of the length of the passage T to be withdrawn from the entrance E of the warehouse W, and the work of taking out the contained object P is completed.

In the above-described storage / conveyance mechanism, since the clamp lift L can grip the stored object in a state where the clamp lift L is not orthogonal to the length direction of the passage T, the width of the passage T is equal to or less than the entire length of the clamp lift L.
Specifically, the space of the warehouse W can be used more effectively for accommodating the contained objects P because the space can be reduced to about half of the conventional one.

Further, in the storage / conveyance device D, the desired storage object P is passed through the passage T.
Even when not located on the side, by operating the remote controller to move the placement discs 7, 7A, the placement discs 7, 7A on which the desired contents P are placed are gripped on the passage T side. Therefore, it is possible to easily move the container P to improve the workability in the operation of taking out the container P, and to use the container P in the old order.

Further, the storage / transportation device D is smaller than an automated warehouse and can be used in a warehouse with a small space. Further, in the accommodating / conveying mechanism using the same device D, it is possible to change the location of the accommodating / conveying device D and add it if necessary.

In addition, in the above-mentioned storage / conveyance mechanism, since the plurality of storage / conveyance devices D can be separately driven and controlled via the remote controller, different types of stored objects P can be simultaneously moved in a plurality of places. The power consumption of the entire mechanism can be small.

The present invention is not limited to the above embodiment,
The following modifications may be made without departing from the spirit of the invention.

(1) In the accommodating / conveying device D of the above embodiment, the base 1
In the corner portion 1a of the mounting disk 7,7A, the circular path R
Rollers 2a of roller conveyors 2, 3 in the direction intersecting with
Since there is a tendency to move on the inner and outer supporting means I, O along the annular path R while slipping the circumferential surface of the 3a in the longitudinal direction, it is necessary to move the mounting disks 7, 7A at the corner portion 1a. The required driving force of the motor 8 increases. Therefore, for example, as shown in FIG. 5, a support member 22 in which a large number of spheres 22a are embedded in the base 22b so as to be relatively rotatable is used for the outer supporting means O corresponding to the corner portion 1a of the base 1.

By doing so, the spherical body 22a of the support member 22 can also rotate in the direction intersecting the annular path R, so that the mounting disks 7, 7A in the corner portion 1a move in the direction intersecting the annular path R on the spherical body 22a. It moves along the ring route R while moving smoothly. Therefore, the mounting disks 7, 7A on the annular path R move more smoothly in the corner portion 1a than in the above-described embodiment, and the mounting disks 7, 7A required for the motor 8 move correspondingly. The driving force for is small. If a similar supporting member is used for the inner supporting member I, the mounting disks 7, 7A can move more smoothly.

(2) In the above embodiment and other examples, the rollers 2a, 3a or the sphere 2
Although the mounting disks 7 and 7A are supported by 2a, it is also possible to support them by the action of electromagnetic force. For example, if a linear motor mechanism is used, the mounting discs 7 and 7A are levitationally supported, so that friction with the supporting means of the mounting discs 7 and 7A is almost eliminated, and when the mounting discs 7 and 7A are moved. But the sound is very low.

(3) Further, a caster may be provided on the lower surface of the mounting disks 7 and 7A as a supporting means separately from each of the above embodiments. For example, casters are rotatably provided at corresponding positions in the lateral direction with respect to the chain 5 on the mounting disks 7, 7A. By doing so, it is not necessary to provide a large number of rollers 2a, 3a or spheres 22a, and the manufacturing cost of the device is reduced.

(4) Placement disk 7,7A on which the operator places the desired contents P
A target mark is attached to a portion of the base 1 corresponding to the gripping position so that it can be easily moved and stopped to the gripping position.

(5) When the contents P are placed on the mounting disks 7, 7A, the contents P
The outer peripheral edge portion of the mounting discs 7, 7A and its inner side are arranged so that the protrusions do not protrude from the outer periphery of the mounting discs 7, 7A to the outside and collide with the contents P on the adjacent mounting discs 7, 7A. This is for the purpose of allowing the worker to place the contents P on the placing discs 7 and 7A by separately painting the portions and different colors.

(6) The number of the mounting disks 7 and 7A is changed at any time depending on the diameter of the stored object P and the space of the warehouse. For example, since the diameter of the winding paper for printing is small among the winding papers, the number of the mounting disks 7 and 7A is changed by using the same size base and the same driving force motor as in the above embodiment. It is possible to set 7 to 10.

(7) A guard is provided to prevent the contained items P placed on the placing disks 7, 7A from tilting. For example, if at least three rod-shaped guard members are provided around the mounting discs 7 and 7A, or if the plate material or the mesh plate is provided in a cylindrical shape or a partially cut-out cylindrical shape, the contained object P is prevented from tilting. To be done. Further, if the height of the guard member is set to such a level that the clamp lift L can grip the stored object P, the grip work of the clamp lift L will not be hindered.

(8) In the above embodiment, the support shaft 6 is fitted in the central hole 7a of the mounting discs 7, 7A, but instead of the mounting discs 7,
If 7A is arranged outside the annular path R and one end of the side surface of the mounting disks 7, 7A is fixedly connected to the chain 5, then only the outer supporting means O need be provided. Even if the mounting disks 7 and 7A are arranged inside the annular path R, the same effect can be obtained.

(9) In each of the above embodiments, the mounting disks 7 and 7A are the support shafts 6.
A central hole that is rotatably supported by a shaft, but instead has a stopper to allow only a certain rotation.
7a may be formed, and the support shaft 6 having a locking portion engageable with the stopper portion may be fitted into the center hole 7a. Then, rotation of the mounting disks 7 and 7A is allowed until the engaging portion of the support shaft 6 is engaged with the stopper portion of the central hole 7a. As a result, the mounting disk 7,7A stops at a certain place, so the mounting disk 7,7A is always
It becomes possible to orient the stored object P placed in the fixed direction in a fixed direction, and during the gripping work of the clamp lift L, the stored object P can be gripped from the fixed direction.
